A wiring harness routing structure includes at least a sub-link arm and a routed line. The sub-link arm includes one end that is rotatably coupled to a vehicle body by using a first coupler, and another end that is rotatably coupled to a door body by using a second coupler, and slidably supports the door body relative to the vehicle body, while rotationally moving relative to each of the vehicle body and the door body. A routed line is routed and provided along the sub-link arm, and connects a vehicle-body-side connector and a door-side connector. In addition, the routed line is routed through a lower side in a height direction of the first coupler that is coupled to the sub-link arm, in a state where the door body has slid to be fully opened.

Wiring harness routing structure, link type sliding door, and wiring harness

A wire harness includes a first protector disposed in a fixed first link, a second protector disposed in a second link relatively rotatable with respect to the first link, a flexible tubular exterior member, and an electric wire inserted through each of the first protector, the second protector, and the exterior member and routed to the second link. A base of the second link is supported by the first link via a rotating shaft such that the second link is relatively rotatable with respect to the first link centering on the base, the first protector includes a first tubular section opened toward the rotating shaft, and a first end portion of the exterior member is fixed to the first tubular section.

Wire harness having improved followability to a rotational motion of a link mechanism

Provided is a harness body that is a wiring component that electrically connects a first electrical connection target installed on a slide door and a second electrical connection target installed on a vehicle body, and is wired along a link mechanism that couples the slide door and the vehicle body and reciprocates the slide door in a sliding direction with respect to the vehicle body; and a harness temporary holding structure at least at one position capable of temporarily holding the harness body assembled to the link mechanism before the link mechanism is assembled to the slide door and the vehicle body.

Wire harness

A harness body () is guided to a fixed portion () on a side of a slide door () by a harness guide tool () at an other end portion () of a first arm member () on a side of a vehicle body () and includes a third routing portion () having a fixing portion () fixed to the fixed portion, a link mechanism () includes a second arm member () on the side of the slide door coupled to the other end portion of the first arm member via a second rotation shaft (), and the third routing portion is twisted and deformed about its own axis between the harness guide tool and the fixing portion when the first arm member and the second arm member are relatively rotated with respect to each other.

A harness body is guided to a fixed portion on a side of a slide door by a harness guide tool at an other end portion of a first arm member on a side of a vehicle body and includes a third routing portion having a fixing portion fixed to the fixed portion, a link mechanism includes a second arm member on the side of the slide door coupled to the other end portion of the first arm member via a second rotation shaft, and a harness guide tool guides a third routing portion toward the fixed portion positioned in a direction intersecting an operation plane of the link mechanism with respect to the harness guide tool itself.

A vehicle door device includes: first and second link arms; a door-side engagement portion that is provided at a close-side end portion of the door that opens and closes a door opening of the vehicle; and a vehicle body-side engagement portion that is provided at a close-side end portion of the door opening that the close-side end portion of the door comes into contact with and separates from, in which one side of the door-side engagement portion and the vehicle body-side engagement portion includes an axial engagement portion extending in a vertical direction of the vehicle, the other side of the door-side engagement portion and the vehicle body-side engagement portion includes a guide groove having a pair of side wall portions, and the axial engagement portion is disposed inside the guide groove at an opening-and-closing operation position in the vicinity of a fully closed position of the door.

Vehicle door device

A vehicular door device causes a door to perform an opening-closing operation, based on an operation of a link mechanism formed of first and second link arms. Further, the first link arm is provided with a hand placement portion that rotates integrally with the first link arm. Then, the vehicular door device is configured in such a way that the first link arm supports a load applied to the hand placement portion.

Vehicular door device

A vehicular door device includes an inclinable lever provided at an open-side end portion of a door opening being opened and closed by a door, based on an operation of a link mechanism formed of first and second link arms, a biasing member that biases the inclinable lever and holds the inclinable lever in an erect state, and a check mechanism that engages with the inclinable lever in the erect state by movement of the door to a full opened position, and holds the door at the full opened position. The first link arm is provided at a position close to the open-side end portion of the door opening by an opening operation of the door, and the check mechanism is provided integrally with the first link arm. Then, the inclinable lever is stored in a clearance between the door and the open-side end portion of the door opening.

A vehicular door device includes a door-side engagement portion including a guide groove that includes a pair of side wall portions facing each other in a vehicle width direction and extends in an opening-closing operation direction of the door, a vehicle body-side engagement portion including a shaft-shaped engagement portion extending in an up-down direction of a vehicle, and an expansion mechanism provided in a second link arm. In an opening-closing operation position near a full closed position of the door where the door-side engagement portion and the vehicle body-side engagement portion engage with each other, the shaft-shaped engagement portion is disposed in the guide groove. The shaft-shaped engagement portion is relatively displaced along an extending direction of the guide groove while a change in length of the second link arm, based on an operation of the expansion mechanism, is accompanied, and thus the door can perform an opening-closing operation.
